This is a brand new save game for Pokemon Picross, intended to be installed with JKSM.
It comes with 5000 Picrites, and the shop can give you more at any time for free, as the flag for having purchased 5000 total picrites has been flipped in the save data.

This effectively removes all in-app purchases from the title, making it possible to play it without being hindered by them.
Enjoy.
